What size wrench is needed for car battery screws?

[LeStephanie]

Generally, the commonly used wrench sizes for removing car batteries are 10mm, 12mm, 13mm, and 14mm. Car battery usage tips: 1. Avoid excessive use of in-car electronic devices: With the increasing number of in-car electronics, while they provide entertainment, they also increase the battery's load. Using them while driving is acceptable, but if used while parked or idling, it will inevitably increase the battery's power consumption, adding to its load and leading to battery depletion, affecting its lifespan. 2. Forgetting to turn off the air conditioning after turning off the engine: Many drivers have this habit—not turning off the air conditioning after shutting down the engine, then letting it start when the car is restarted. Unbeknownst to them, this method causes an instantaneous high power demand on the vehicle, and over time, it also wears out the battery. 3. Frequent vehicle starts in a short time: Especially in winter, when the car is hard to start, if the first attempt fails, do not rush to restart repeatedly. The interval between each start should be at least 3 seconds; otherwise, it can cause excessive battery discharge and damage.
